[RE-wrenches] AC Coupling Xantrex XW Inverters to Enphase Microinverters

[Jason Szumlanski]

I read the application note here:

http://www.global-download.schneider-electric.com/852577A4005D7372/all/8
FA29D94B918A0FB8525781F0072FCA7/$File/ac-coupling-app-note(976-0240-01-0
1_rev-a).pdf

 

...and I contacted Xantrex to make sure the application note applies to
other brands of grid-tie inverters. It does according to the rep I spoke
with.

 

I just wanted to find out if there is any real world experience out
there with Enphase and the XW series AC coupled. I have a customer with
three XW4024's in single phase configuration set up as a battery backup
only now. He wants to add up to 10kW. I suggested Enphase as an AC
coupled system (mainly due to the distance to the proposed array). I'm
aware of the pitfalls noted in the application note regarding high limit
shutoffs. Any thoughts?
